Explain plan for: select min(t1) from test where t2=4;
was resolved using the index only so I think that will be very efficient.

why would you want to create function based index on a column that you are
not using in the where clause.
for your sql statement a index on cnfr_no would work great...

I have the following statement that I would like to create a
function-based
index for:
SELECT MIN(tran_dt)
FROM ach_tran
WHERE cnfr_no = :b1
I'd like the index to include columns cnfr_no and tran_dt (in that
function-based
index for:
SELECT MIN(tran_dt)
FROM ach_tran
WHERE cnfr_no = :b1
I'd like the index to include columns cnfr_no and tran_dt (in that
The examples I've seen are
just single-column indexes. Is it possible to have this additional
column in a function-based index that
is not involved in the actual function? If yes, what would the index
creation statement look like?
This is version 9.2.0.1 on Sun Solaris 2.6.
Thanks in advance for any assistance.
